+# Mocking
+
+## Mock Functions
+
+```ts
+import { expect, vi } from 'vitest'
+
+// Create mock function
+const fn = vi.fn()
+fn('hello')
+
+expect(fn).toHaveBeenCalled()
+expect(fn).toHaveBeenCalledWith('hello')
+
+// With implementation
+const add = vi.fn((a, b) => a + b)
+expect(add(1, 2)).toBe(3)
+
+// Mock return values
+fn.mockReturnValue(42)
+fn.mockReturnValueOnce(1).mockReturnValueOnce(2)
+fn.mockResolvedValue({ data: true })
+fn.mockRejectedValue(new Error('fail'))
+
+// Mock implementation
+fn.mockImplementation((x) => x * 2)
+fn.mockImplementationOnce(() => 'first call')
+```
+
+## Spying on Objects
+
+```ts
+const cart = {
+  getTotal: () => 100,
+}
+
+const spy = vi.spyOn(cart, 'getTotal')
+cart.getTotal()
+
+expect(spy).toHaveBeenCalled()
+
+// Mock implementation
+spy.mockReturnValue(200)
+expect(cart.getTotal()).toBe(200)
+
+// Restore original
+spy.mockRestore()
+```
+
+## Module Mocking
+
+```ts
+// vi.mock is hoisted to top of file
+vi.mock('./api', () => ({
+  fetchUser: vi.fn(() => ({ id: 1, name: 'Mock' })),
+}))
+
+import { fetchUser } from './api'
+
+test('mocked module', () => {
+  expect(fetchUser()).toEqual({ id: 1, name: 'Mock' })
+})
+```
+
+### Partial Mock
+
+```ts
+vi.mock('./utils', async (importOriginal) => {
+  const actual = await importOriginal()
+  return {
+    ...actual,
+    specificFunction: vi.fn(),
+  }
+})
+```
+
+### Auto-mock with Spy
+
+```ts
+// Keep implementation but spy on calls
+vi.mock('./calculator', { spy: true })
+
+import { add } from './calculator'
+
+test('spy on module', () => {
+  const result = add(1, 2) // Real implementation
+  expect(result).toBe(3)
+  expect(add).toHaveBeenCalledWith(1, 2)
+})
+```
+
+### Manual Mocks (__mocks__)
+
+```
+src/
+  __mocks__/
+    axios.ts      # Mocks 'axios'
+  api/
+    __mocks__/
+      client.ts   # Mocks './client'
+    client.ts
+```
+
+```ts
+// Just call vi.mock with no factory
+vi.mock('axios')
+vi.mock('./api/client')
+```
+
+## Dynamic Mocking (vi.doMock)
+
+Not hoisted - use for dynamic imports:
+
+```ts
+test('dynamic mock', async () => {
+  vi.doMock('./config', () => ({
+    apiUrl: 'http://test.local',
+  }))
+  
+  const { apiUrl } = await import('./config')
+  expect(apiUrl).toBe('http://test.local')
+  
+  vi.doUnmock('./config')
+})
+```
+
+## Mock Timers
+
+```ts
+import { afterEach, beforeEach, vi } from 'vitest'
+
+beforeEach(() => {
+  vi.useFakeTimers()
+})
+
+afterEach(() => {
+  vi.useRealTimers()
+})
+
+test('timers', () => {
+  const fn = vi.fn()
+  setTimeout(fn, 1000)
+  
+  expect(fn).not.toHaveBeenCalled()
+  
+  vi.advanceTimersByTime(1000)
+  expect(fn).toHaveBeenCalled()
+})
+
+// Other timer methods
+vi.runAllTimers()           // Run all pending timers
+vi.runOnlyPendingTimers()   // Run only currently pending
+vi.advanceTimersToNextTimer() // Advance to next timer
+```
+
+### Async Timer Methods
+
+```ts
+test('async timers', async () => {
+  vi.useFakeTimers()
+  
+  let resolved = false
+  setTimeout(() => Promise.resolve().then(() => { resolved = true }), 100)
+  
+  await vi.advanceTimersByTimeAsync(100)
+  expect(resolved).toBe(true)
+})
+```
+
+## Mock Dates
+
+```ts
+vi.setSystemTime(new Date('2024-01-01'))
+expect(new Date().getFullYear()).toBe(2024)
+
+vi.useRealTimers() // Restore
+```
+
+## Mock Globals
+
+```ts
+vi.stubGlobal('fetch', vi.fn(() => 
+  Promise.resolve({ json: () => ({ data: 'mock' }) })
+))
+
+// Restore
+vi.unstubAllGlobals()
+```
+
+## Mock Environment Variables
+
+```ts
+vi.stubEnv('API_KEY', 'test-key')
+expect(import.meta.env.API_KEY).toBe('test-key')
+
+// Restore
+vi.unstubAllEnvs()
+```
+
+## Clearing Mocks
+
+```ts
+const fn = vi.fn()
+fn()
+
+fn.mockClear()       // Clear call history
+fn.mockReset()       // Clear history + implementation
+fn.mockRestore()     // Restore original (for spies)
+
+// Global
+vi.clearAllMocks()
+vi.resetAllMocks()
+vi.restoreAllMocks()
+```
+
+## Config Auto-Reset
+
+```ts
+// vitest.config.ts
+defineConfig({
+  test: {
+    clearMocks: true,    // Clear before each test
+    mockReset: true,     // Reset before each test
+    restoreMocks: true,  // Restore after each test
+    unstubEnvs: true,    // Restore env vars
+    unstubGlobals: true, // Restore globals
+  },
+})
+```
+
+## Hoisted Variables for Mocks
+
+```ts
+const mockFn = vi.hoisted(() => vi.fn())
+
+vi.mock('./module', () => ({
+  getData: mockFn,
+}))
+
+import { getData } from './module'
+
+test('hoisted mock', () => {
+  mockFn.mockReturnValue('test')
+  expect(getData()).toBe('test')
+})
+```
+
+## Key Points
+
+- `vi.mock` is hoisted - called before imports
+- Use `vi.doMock` for dynamic, non-hoisted mocking
+- Always restore mocks to avoid test pollution
+- Use `{ spy: true }` to keep implementation but track calls
+- `vi.hoisted` lets you reference variables in mock factories
